Question

I am following this tutorial http://developers.facebook.com/docs/appsonfacebook/tutorial/
and specifically at this part of code

 $app_id = "YOUR_APP_ID";
 
 $canvas_page = "YOUR_CANVAS_PAGE_URL";

 $auth_url = "http://www.facebook.com/dialog/oauth?client_id=" 
        . $app_id . "&redirect_uri=" . urlencode($canvas_page);

When I enter $canvas_page as

$canvas_page = "http://www.facebook.com/PAGE_NAME/app_APP_ID/"

I get an "Error occured. Try again Later"

If I enter Canvas Page Url instead, it shows the canvas page correctly but I do not want that.

I am sure that it was working last week, so I do not know what is wrong now.

Answer 1

What was previously working was this

$canvas_page="http://www.facebook.com/pages/PAGE_NAME/PAGE_ID?sk=app_APP_ID"

but since I changed the app to a namespace I had to do something like this:

$canvas_page="http://apps.facebook.com/APP_NAMESPACE/" 

and it now shows up correctly without error
